A unified model of feed rotation in radio telescopes and GNSS antennas
Joe Skeens, Johnathan York, Leonid Petrov +3
We describe a model that accounts for the phase rotation that occurs when a receiver or transmitter changes orientation while observing or emitting circularly polarized electromagn…

Extracting Geodetic Data from GNSS-VLBI Co-Observation
Joe Skeens, Johnathan York, Leonid Petrov +3
We have been developing a novel interferometer formed directly between a Very Long Baseline Interferometry (VLBI) radio telescope and a Global Navigation Satellite Systems (GNSS) a…

First observations with a GNSS antenna to radio telescope interferometer
Joe Skeens, Johnathan York, Leonid Petrov +5
We describe the design of a radio interferometer composed of a Global Navigation Satellite Systems (GNSS) antenna and a Very Long Baseline Interferometry (VLBI) radio telescope. Ou…
